If it has the ( ) it a u if it has |x| it’s a v
2(p+1)=24
divide both sides by two
p+1=12
subtract 1 from both sides
p=11
Answer:
y - 3 = a(x + 1)^2
Step-by-step explanation:
The vertex equation of a vertical parabola is:
y - k = a(x - h)^2.
If the vertex is at (-1, 3), then the equation becomes:
y - 3 = a(x + 1)^2, where a is a constant.
Next time, would you please share the answer choices. Thank you.
Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
There is 50mL of liquid altogether.
35mL is not chocolate.
35/50 is not chocolate.
35/50 = 70/100
70/100 = 70%
70% of the mixture is not chocolate.
